Abstract

A method of manufacturing three-dimensional objects by laser sintering is provided, the object is formed by solidifying powder material layer by layer at locations in each layer corresponding to the object by means of laser radiation, wherein an IR-radiation image in an applied powder layer is detected, characterized in that defects and/or geometrical irregularities in the applied powder layer are determined on the basis of the IR-radiation image.
